Abstract：Strip shape is a vital indicator of the geometric dimensions in the rolling process of strip. Twodimensional rolling theory used previously can not meet the present rolling requirement because it has no considerations on transverse deformation. To master the threedimensional deformation regular and establish the relationship between exit thickness and various technological factors is the most important thing for setting up control of shape. Based on the relative theory, roll deformation was calculated by influence function and the strip plastic deformation was also calculated by the threedimensional function. The result of roll deformation can provide exit thickness transverse distribution for strip plastic deformation, similarly the strip calculation result can provide roll pressure to roll deformation calculation, and finally iterations are completed by several loops within a certain accuracy scope. Combined with practical situation, the model accuracy was verified, further the model calculation can lay solid foundations for online calculation of roll gap.
